We installed the new update, and it worked PERFECTLY! We were so excited. It

had never worked so well. We were able to scratch the video back and forth

with only minor frame loss, and it played forward perfectly. After many

hi-fives and cheers, we called it a night.



The next day, we hooked up our USB midi foot controller, and we started to

experience the same problem we were having previously, with the frame rate

dropping. Assuming it was the foot controller, we unplugged the foot pedal

and re-started the program and the computer. Unfortunately, we were unable

to get it to work properly again.



Then, we started noticing the above errors when restarting the program.

Hopefully they help.



If we do not have our Final Scratch 2 interface hooked up to the computer,

the video in maxi-patch plays perfectly at full frame rate.



Also, in re-reading our other post, we noticed that we had not included our

in and out vector size. Any recommendations? We found our computer will

accept up to 2048 on the I/O Vector setting, and up to 1024 on the Signal

Vector size. We tried pushing the Signal Vector size to 2048, but it crashed

the program. Is there an ideal size? Will vector size the affect frame rate

in any way?



Thanks so much,



cb and Jesus

Jesus-



Thanks for the detailed error reports. I will look into why the .jpg images don't seem to be found.... but that should not effect framerate at all. The errors that are being reported shouldn't matter at all to the program's framerate performance.



I still need you to answer these two questions:



1) Which version of OSX are you using? Hopefully 10.4.3 (or higher). If you're still using Panther (10.3.X) then you should upgrade to Tiger immediately.



2) What are your "Energy Saver" System control settings? Specifically, under the "Options" tab you will see a menu where you can select "Processor Performance". Make sure "Processor Performance" is set to "Highest". If it's set to "Automatic" that could explain why sometimes your framerates are high and other times they slow down.



Regarding "I/O Vector Size": It should work just fine if you set I/O Vector Size to 128 or 256. Also make sure that "Signal Vector Size" is set to the same value as "I/O Vector Size".



Thanks!
